the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...

simulation of rough rice drying is one of the proper methods for predicting moisture distribution in the product, and throughout the process of drying. the drying process must be well understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. therefore, an accurate understanding and description of the drying mechanis...

serum albumin is the most abundant protein in blood plasma. its two major roles are maintaining osmoticpressure and depositing and transporting compounds. in this paper albumin-ethanol/water solutionssimulations are carried out by three techniques including monte carlo (mc), molecular dynamic (md) andlangevin dynamic (ld) simulations in aqueous solutions. investigation the energy changes with t...

surfactant molecules are used as interesting tools to study the structure, function and stability of proteins. protonation states of amino acids may be changed in the presence of surfactants. in this work, using experimental observations and molecular dynamic simulation, the effects of sodium dodecyl sulfate on the acid dissociation constants of tryptophan was examined. the acid–base equilibriu...

introduction: the aim of this innovative study was to regenerate a condition that makes it possible to carry out researches in the field on a variety of resorption. materials and methods: in order to develop apical resorption, the root canals of selected teeth were instrumented and then drilled with #4 gates glidden drills. in the next stage, the teeth were submerged in melted rose wax up to 3 ...

a model describing the main processes occurring in the uasb reactor was developed; in orderto maintain simplicity and applicability of the model, only the fundamental aspects were considered. in themodel, the reactor is divided in several well-stirred reactors coupled in series and it comprises substratedegradation, biomass growth and the reactions that take place within the granules. the impor...

abstract the propose of this study was evaluation of cropsyst model on growth simulation and yield stimation of canola under different irrigation treatments. canola (talaye) was sown under 5 treatment and 4 replicants in completed randomized block designs at the college of agriculture, shiraz universityduring 2007-2008. during the growth season dry mass and lai was meseaured frequently, then mo...
